Review actions performed after component unmounts (cleanup react errors)

[underfisk]

There might be some parts that are attempting to perform some kind of update when the component unmounts or has an invalid/outdated state, i have to review those parts to avoid leaks

Stack error example:

eval | @ | useKeyboard.js?76d1:77
  | eval | @ | ApolloSpreadsheet.js?5c34:formatted:112
  | eval | @ | ApolloSpreadsheet.js?5c34:formatted:128
  | eval | @ | ClickAwayListener.js?15d1:91
  | eval | @ | useEventCallback.js?4234:14

It seems to be happening on-grid clear focus, we should use a ref rather than a state for isFocused and also ensure that we only set state if component is mounted
